MOUTHPIECE.

Application flied Dctober 26, 1821. Serial No. 510,488;

To all whom it may concern: Y

Be it known that I, Gnome A. HIGH- rmnn, a citizen of theUnited States, resid-.

ing at Scranton, in the county of Lacka- 5 wanna and Stateof Pennsylvania, have in vented certain new and useful Improve-- meats in Mouthpieces, of which the following is a specification, reference being had to the accompanying drawings. 7

This invention relates to certain improvements in mouth-pieces and has relation more particularly to a device ofthis general character especially designed and adapted for use in connection with smoking pipes or is the like, and it is an object of the invention to provide a device of this general character having novel and improved means whereby moisture is prevented from passing inwardly through the mouth-piece.

Another object of the invention is to provide a novel and improved mouth-piece of this general character embodying a valve serving to close the bore of the mouth-piece against the passage "of moisture" outwardly therethrough.

The invention consists in thedetails of construction and in the combination and arrangement of the several parts of my improved mouth-piece whereby certain importaut advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.'

In order that my invention may be the better understood, I willnow proceed to de scribe the same with reference to the acco 40 panying drawings, wherein:

Figure 1 is a fragmentary view in elevation illustrating a mouth-piece constructed in accordance with an embodiment of my invention;

Figure 2 is a view in top plan of the device as illustrated in Figure 1;

Figure 3 is an enlarged fragmentary view taken longitudinally through the outer end of the mouth-piece as herein embodied; and

Figure 4 is a sectional view taken through the valve member or cap.

As disclosed in the accompanying drawings, 1 denotes the stem of the mouth-piece of any ordinary or preferred design and whichis provided at its eduction or outer end with an outstanding'nipple 2 defining the bore 3 of the stem.

The outer endvof the nipple 2 is formedto provide a concave valve seat 4 with which is associated a disc or valve 5 The disc or valve 5 comprises a concavo-convex metallic disc 6 with its concave face outwardly directed.

Thread ed or otherwise engaged with the nipple 2 1s a cap 7, said nipple 2 extending within a socket 8, the inner end of which terminates outwardly of the inserted end of the nipple 2 whereby a chamber 'a is provided. In communication with the chamber a and preferably at diametrically opposed points are the ports 9 disposed on an outward incline and opening through the inner face of the cap 7. I

When t e cap 7 is applied, the outer open ends of the ports 9 register with the recesses 'or bypasses 10 formed in the outer end of the stem 1 and in communication with the atmosphere.

In practice, as the smoker draws through the mouthpiece, the disc or valve 5 will open sufliciently to permit the smoke to ass into the chamber a and into the mouth of the smoker through the ports 9 and the bypasses 10. The particular formation of the valve or disc 5, however, causes the same to engage the'seat 4 under normal conditions and effectively provides means whereby moisture cannot pass inwardly through the stem 1 and into the pipe below or to an applied cigar or cigarette should the mouthiece be employed in connection with a older.

'By this arrangement, the fouling of the stem is prevented and the same can also be readily and thoroughly cleansed upon removal of the cap 7.

From the foregoing description it is thought to be obvious that a mouth-piece constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:

1. A mouth-piece having a nipple defining the outer end of its bore, ,a member coacting with the nipple to prevent inward flow through the bore of the mouth-piece, and a cap overlying the outer end of the mouth-piece and provided with a socket to rcceivethe nipple, said outer end of the mouth-piece being provided with bypasses for communication with the atmosphere, the cap having ports communicating with the socket outwardly of the nipple and with the bypasses.

2. A mouth-piece having a nipple defining the outer end of its bore, a member 00 acting with the nipple to prevent inward flow through the bore of the mouth-piece, and a cap overlying the outer end of the mouth-piece and provided with a socket to receive the nipple, said outer end of the mouth-piece being provided with bypasses for communication with the atmosphere, the cap having ports communicating with the socket outwardly of the nipple and with the bypasses, the outer'end of the nipple being concave. the coacting portion of the member being convex.

3. A mouth-piece having a. nipple de fining the outer end of its bore, a member coacting with the nipple to prevent inwardflow through the boreof the mouth-piece, and a cap overlying the outer end of'the mouth-piece and provided with a socket to receive the nipple,'said outer end of the mouth-piece being provided with bypasses for communication with the atmosphere, the cap having ports communicating with the socket outwardly of the nipple and with the bypasses, the outer end of the nipple being concave, the member being ooncavoconvex with the concave face outwardly disposed.

4. A mouth-piece of the class described having an internal chamber at the outer end GEORGE A. H'IGHFIELD.
